MACHINE FOR WEAVING COVERINGS FOR WHIP=HANDLES.v

Speoiii cation forming part of Lettersiatent No. 52,718, dated February20, 1866.

l'o all whom it may concern:

Be it known that I, LIVERAS, HULL, of Charlestown, of the county ofMiddlesex and State of Massachusetts, have invented a new and usefulMachine for Making the Coverings of Whip-Handles; and I do herebydeclare the same to be fully described in the following specificationand represented in the accompanying drawings, of which- Figure l is atop view, Figs. 2 and 3 are side elevations, and Fig. 4 is a verticalsection, of it.

The said machine is intended to wind one or more threads in a helixaround a whipstock and to connect the coils of the helix by otherthreads bent or twisted together on each helix. These connecting-threadswhile being interlaid with the covering-threads may by the machine becaused to arrange themselves in helices going about the whip-handle.

In the drawings, A denotes the frame of the machine, it being suitablymade for giving support to the operative parts.

The rst constituent portion of the machine is"a mechanism for sustaininga whip-stock or article to be covered and moving it vertically, ascircumstances may require.

In the drawings the whip-stock is represented at B as having its butt orlarger end inserted in a socket, or in the upper end of a vertical rod,C, which is so supported within bearin gs b c as to be capable of beingrevolved and moved lengthwise therein. The lower part of the rod has aseries of grooves formed around itat equal distances apart, as seen atd. A pinion gear, e, engages with these grooves, which form acylindrical rack, such pinion being fixed on a tubular shaft, 0', whichrevolves on a horizontal shaft, f, that receives rotarymot-ion from adriving-shaft, g, by means of a train of gears, 7L t', an upright shaft,k, a

plied to the shaft s', and the gear u', serves to engage the said gear uwith the shaft s', as occasion may require.

By means of the worm c', the gear uf, the shafts', the cone-pulleysp q',the endless band r', the shaft o', and the gear e an upward verticalmotion may be imparted to the rod or shaft C and a whipstock when fixedtherein, and the degree of the motion may be varied by shifting the belton the cone-pulleys.

The next constituent part of the machine is the mechanism for windingone or more threads in a helix about the whip-stock during its` upwardmovement, the same being described as follows:

A bent arm, D, projects from an annulus, E, arranged horizontally and onthe frame of the machine. This annulus serves to support the spindles mmof two or any oth er suitable number of spools, a a, from which, whenthe machine is in action, threads pass to and through an eye at theinner end ofthe arm D, and from thence to the whip-stock. By giving`arotary motion to the annulus E the threads will be moved about thewhip-stock during its upward movement. This rotary motion of the annulusE is effected by means of gears o p, one of which is aiiixed to theannulus and the other to the upright shaft k.

The next portion or constituent part of the machine is a mechanism forlaying the binding or connecting threads about the helixcoils, themachine, as represented in the drawings being made to exhibit four setsof such mechanism. There may be more or less of them,as circumstancesmay require. As they are alikein action and construction, thedescription of one of them will suffice to answer for all. In eachentirerevolution of the thread-carrying arm D it will pass through each ofthese sets, so as to lay its thread or threads successively into theangles of decussat-ion of the threads of the said sets, and immediatelyor soon after the threads have been so laid between any two of thebinding-threads of any one set, as above described, such set will berevolved so as to lay the binding-thread around the covering-thread orthreads and twist such binding-threads together.

Each of the said sets has a pair of two separate dier-frames, q r, eachof which is provided with a semi-cylindrical journal, s. Thesesemi-journals are supported in semi-boxesv extends to the whip-stock.

t u, one, lt', of which extends down from a stay tionary annulus, o,while the other is supported So as to be capable ot' being moved up anddown, the downward movement being effected at the proper time by a cam,fw, which projects from the rotary annulus E, and works against a stud,a', extended from the shank y of the semi-box. A spring, z, applied tosuch shank serves to effect the upward movement of the bearings. Each ofthe said semi-journals carries two half-gears, a b', arranged on it, asrepresented. A train of two gears, c d', is applied to each flier-frame.One of such gears is fastened on the end of the l'lier, and the trainengages with the inner semi-gears, b b, and during rotary motion of thepair or flier-frames q roperates toproduce a rotary motion ot' theseiiiers. This rotary motion of the dier is for the purpose of preventing`the thread of its bobbin from becoming further twisted.

Each flier carries a spool, e', supplied with a proper thread-tensionerand delivering ap paratus, f, through which the thread passes from thespool to and through the nose of the liier, and from thence through thenose g of the flier-frame. From the latter'the thread To the annulus E acurved rack, 7L', is fastened. This rack, during each revolution ofthesaid annulus, engages in succession with the external pairs ofsemi-gears of the several pairs of iiier-flames, and produces arevolution of each ofthe said frames. The thread-carrying arm D, duringits circuit of revolution, passes between each pair of Hier-frames, thelower frame of such pair being moved downward or away from the upperframe to.allow of the passage of the arm D between such frames. Afterthe arm D, carrying the covering-thread, may have so passed each pairot' Hier-frames, so as to carry the threads into the vertex of the anglebetween the two binding-threads of such flier-frames., the saidHier-frames arc to be revolved so as to interlock their threads or twistthem ou the covering-thread.

If the whip-stock be simplymoved vertically during the operation of'working the covering on its handle, the binding-threads would lay on itin vertical courses or ranges; but in order that each of them may belaid on it in a helix, the whip-stock should have a proper rotary motionwhile heilig moved vertically. The machinery for et't'ectin g this is anauxiliary to the main part or combination on which my invention isbased, and may be thus described.

A friction-clutch, h2, operated by a lever, t', is xed on the shaft orrod C, and engages with a beveled wheel, 7c', which is placed on and soas to be capable of freely revolving on the shaft c. This beveled gearis revolved by another beveled gear, l. and the gears h t', thelatter-viz., lbeing fixed on the shat'tf.

When the clutch h2 is out of action on the bevel-gear 7c such gear willbe freely revolved on and will produce no rotary motion of the shaft orrod C, but when the clutch bears on the wheel and the latter is in theact of being revolved the rod C will be slowly rotated.

The machine when in operation without the whip-handle or its equivalentplaced within it will make a braid or cord.

I claim as my inventionl. A mechanical combination comprised not only ofmachinery for sustaining a whip-stock or other article and moving itlengthwise and mechanism for winding one or more threads in a helixabout the whip-stock or article while being s0 moved, but also ofmechanism for laying binding or connecting threads about thehelix-coils, the whole being sul'istantially as herein before described.

2. In combination therewith, mechanism for revolving the whip-stock soas to cause the binding or connecting threads to be laid in a helixthereon, as set forth.
